TIE-@LATE The present invention relates to new andv useful improvementsin railway roadbed appliances and has particular reference to a new andimproved tie-plate for supporting railway rails on wooden ties or thelike.

The primary object of my invention is to provide a tie-plate of theclass described having meansfor reinforcing the rail holding element,which in the present instance would be the usual spike, means forpreventing lateral displacement of the rail, and means for preventingskidding of the tieplate on the tie.

Another object of my invention is to provide a tie-plate of the classdescribed formed from a single casting with the element mentioned in theforegoing associated therewith whereby to reduce the cost of manufactureof such devices without materially reducing their effectiveness.

Other objects and advantages to be derived from the use of my inventionwill appear from the following detail description and the claim, takenwith an inspection of the accompanying drawing, in which Figure 1 is aperspective view of a rail and tie showing my improved tie-plate appliedin operative position;

Fig. 2 is a top plan view of the same; and

Fig.`8 is a bottom' plan View of the same.

Referring more particularly to the drawing, wherein similar charactersof reference designate like and corresponding parts throughout thevarious views, 1 designates the body portion of my invention which isrectangular in configuration in the -preferred form of the device. Theintermediate portion of the plate l receives a rail, a plurality ofintersecting grooves 2 being diagonally arranged on the upper face ofsaid plate to permit moisture to drain between the rail and the plate.

The upper face of the plate l is also provided with reinforcingelements, said reinforcing elements being formed of lugs 3 havingvertical walls thereof arranged adjacent apertures et formed in saidlate.

These lugs 3 serve to reinforce the rail' old` lthe plate 1, saidvmanently collect between the specification of Leiters ratent. PatentedSept, g5, 1191"; Application filed May 23, 1916.

ing elements which in the present instance are the usual spikes 5, bestshown in Fig. 1. An intermediate reinforcing lug 6 is providedhaving thevertical end wall thereof engaging a rail. It will be seen that in theprovision of the lug 6 I afford means for preventing spreading of therails, one of the most predominant causes of wrecks on railways at thepresent time, this lug 6 being found particularly useful when used inconnection with the outside rail on a curve. A second pair of apertures7 are provided in at a distance fromt ie apertures 4 and being adaptedto receive spikes or similar fastening elements.

The under side of the plate 1 is provided with a plurality ofintersecting diagonally arranged ribs 8 and 9, there being sets of eachat each end forming a chamber 10 approximately centrally of the underface of the plate whereby to form means for preventing lateral or.longitudinal displacement of the plate on the tie. It will be obvious`that when the spikes are driven home the chamber 10 forms a suction onthe tie assist' ing in maintaining the plate against displacement. InFig. l I have shown a rail way rail 11 of the usual formation and a.ltiev l2. In the present instance the tie isl formed of wood, but, ofcourse, it will be understood that various. materials may be substitutedtherefor. A pair of flanges 13 and 1.4L extend along the longitudinalmarginal edges of the plate 1 and extend downwardly from the .under facethereof, said iianges assisting in preventing lateral displacement ofthe tie plate.

In the use of my improved tie plate it will be seen that not only arethe A@staining elements, such as the spikes 5, prevented from distortionunder strain, but the rail itself is prevented from being laterallymoved, ordinarily termed spreading In manu faoturing my device the costwill not be materially increased over the cost of the tieplate now inuse, but the effectiveness of the device is materially increased. Itwill be readily apparent that no moisture can perrail and the tie owingto capillary action, which in the present instance is the drain 2.

From the above description taken in connection with the accompanyingdrawing,it

is thought that a clear and comprehensive a ertures being arrangedprevented by means of' understandingI of the. construction, operationand advantages of my invention may be had, and while I' have shown anddescribed my invention as embodying a specific strucv ture, I desirethat it be understood that I may make such changes in structure as donot depart from the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

The combination in a tie plate of the class i t. described, of a bodyportion having a pair of openings on each side thereof, lugs formed onthe said body portion adjacent the rear., edges 0i the openings on theuppei face thereof, a reinforcing lug formed intermediate the said lugsfor engagement with a rail, Ythe said body portion being provided with apair of intersecting recesses terminating at a pointl adjacent the outeredge of the formed by the intersecting of the said ribs. to preventdisplacement of the plate on thi.1

tie. v

In testimony whereof, Iaiiix my signature hereto.
